Still seems a bit low. I get 94-99% utilization on my 7950, which is good for 8.5k PPD stock clocks. If you aren't seeing 94-99% utilization, it's probably your AMD GPU drivers, they have had issue post 12.8. There is a thread here with more info.
For the CPU, you will probably want to run SMP -5, which should still load up each core 85-95% with the GPU going. I would concentrate on getting the GPU folding at a steady 94-99%, then experiment with SMP -5, or SMP -6.
